MEANS ron MOUNTING PUNCTURELESS TIRES N WHEEL-mms.

.To all` whom it may concern: i

Be it known that I, BENJAMIN DAHL, of

'rl\fl inneapolis,` Hennepincounty, Minnesota,

have' invented certain new and -usetul Im# provements 1n Means for Mounting Puncturel'ess Tires on Wheel-Rims, of which thei following is a specication.

This invention relates 'to puncturless tires .in'wliich a ller of yielding, gelatinous material'is employed and put underfcompression when the casing 1s mounted on the wheel rim.

Generally in pneumatic tires the bead or' locking ring may be forced into place with the .hands without `the use of any compressf ingmeans, but where a filler is used that is put under compression by drawing together ftheedges ofthe casing it has been found that `the clamping means cannot be applied' to the ordinary bead without bending or buckling it to such an extentthat diiiiculty is experienced in putting the ller under compression.

The object, therefore, oir' my invention is to provide a bead of such construction that a suitable number of clamps may beapplied thereto and the filler squeezed to till the casino' wit-hout twisting or'b'ending the bead(V out o shape.

` land described. j

In the accompanying" drawings forming .part of this specification, Figure l isa detail 'sectional view illustrating the manner of applying the clamp to a tire containing a4 -punctureless filler, Fig 2 1s a perspective view of aportion of the bead, Fig. 3 is a de- `tail sectional view showing the invention ing shown in Fig. 3.

applied to another ferm of tire, Fig. 4 is a' erspective view of a portion of the bead in its modified form, as used with the tire cas- In the drawing, 2 4represents .the metal rim of the wheel, 3 the felly and 4 the outer casingfof the tire. The rim has a flange or rib 5 on one edge and an annular depression "6 in its opposite edge Vterminating in a flange 7. .A bead 8 is seated against the rib 5 and engages the edge of the tire casing 1n the Specction of Letters Patent.4

of the tire', a bead 9 is provided,'grooved to t the bead of the casing and also havi Aon its outer surface an annular boss 10 w ich serves to -strengthenand stien the bead against bending or buckling when under pressure.

11 is a split locking ring which is adapted to be inserted' between the bead 9 and the flange 7 `to lock the parts to ether. The boss 1.0 preferably has a groove outer face 12 to form a seat for a 'screw 13 that v is carried lby a frame lwhich extends across the plane of the wheel, as shown in Fig. l, and is provided with a fixed jaw 15` to engage the flange 5.. Generally the beads and thelock-l ing ring may be forced into place by hand',

1n the' case of. a pneumatic tire, but wherel it is necessary to use a clamp or a series of.A

them to'putthe filler under suflicient compression to allow the locking ring to be slipped into its seat.` Thisl have been able .to accomplish by means of the annular boss A' on the bead 9 having a 'seat to receive the My invention consists generally in the' improved yform :of bead hereinafter shown screw or movable-jaw 13.

In Fig. 3 a slightly modified construction I is shown, in which the roove in the inner 'face of the bead 9 islle Awith some suitable material to present a rounded surface to fit the curved surface of the casing. This bead 'I .will designate by the referencenumeral 416. lt is equipped with a boss, as described with reference to Fig. 1, and the compression of the filler is obtained in substantially 'the same manner. y

I do not wish to be conned to the form of the bead employed or the .shape of the boss, as both are capable of modificatlon withtion. I I claim as my invention v The combination with'a wheel vrimadapt-- ed to'be used with an outer casing having a filler'off yielding material within theaame, of beads arranged to engage said, casing to.
